CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 337,949, dated March16. 1886.

Application filed January 5, 1886. Serial No. 187,666. (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS A. GRIFFIN, of Chicago, in the county ofCool; and State of Illinois, have invented a new and useful Im provementin Oil-Boxes, of which the following is a full, clear, and exactdescription.

My invention is adapted specially to sliding box-lids, though it may beotherwise advantageously applied. The ordinary sliding lid is withoutprojections on its inner surface, this construction being necessary toallow it to pass the upper edge of the journal-box. Asa consequence,much of the oil thrown against the lid while the journal is revolvingwill escape unless the joint between the lower edge of the lid and boxis made tight by planing both the lid and its seat, and even then someoil will still escape.

To prevent this waste of oil is the object of my invention, whichconsists of a shield or apron, cast or otherwise conveniently applied,which serves to prevent the slopping of the lubricant, and returns thesame to the fount or oil-box proper.

In the accompanying drawings, Figure 1 is a section of ajournal-box; andFig. 2 is a perspective of alid ready for insertion, showing itsconstruction more clearly.

A is alid having upon its inner face, near its lower edge, the recess B,large enough to contain the strip or apron C, so that when it is foldedback into the recess nothing projects from the inner face of the lid,which can be readily inserted in position. The apron C is madeofsheet-iron, tin-plate, or other flexible metal. Its length is slightlyless than the width of the opening in thejournal-box, and it is of anydesirable widthsay one to one and onehalf inch-and itshould be thinenough to per- I init of bending. Its lower corners may be truncated, orthe recess for the apron or shield may be made so large as to allow forthe insertion of the fingers or tool used in bending it out.

To put the apron G into a cast lid, I insert it into the mold after thepattern is removed, burying all of it in the sand,except a portion ofthe upper edge,which is left projecting into the interior of the mold,so that the castiron,when poured.becomes firmly united with it. Onremoval from the mold the apron is folded back into the recess. Afterthe partial insertion of the lid in the box, so that the apron O is pastits upper edge,D, the apron is bent outwardl y from its recess,so as toproject into the box. The apron need only be bent back into said recesswhen it is desired to entirely remove the lid, as it can be opened forordinary purposes without doingso. NVhen the lid is entirely closed, theparts have the relative positions shown in Fig. 1, it being evident thatthe oil thrown against the boxlid must be returned again to the fount oroilbox proper.

My invention may be applied to hinged lids with advantage, for the apronO is lighter and less expensive than alip cast on the box would be.

I claim The flexible apron O, constructed substantially as and for thepurpose described.
